i started using gh at 2 ius a day for 2 weeks. then went to 3 ius for one week, with no problems. then went to 4 ius a day for one week. thats when my hands started to get a little numb. so i backed down to 2 ius a day and my hands have had that numb feeling for 3 weeks after i went to the 2 ius a day. should i be worried, is this normal, is there anything else i can do>???? please help. it is my 1st time with gh.....thx
